TOOL FOR REMOVlNG VALVE PARTS.

APPLI CATION FILED 001130. 1917.

Patented ept 3, 1918.

lie it known that Gannon 3 Prices, at citien of the llnited States of iuuerica, residing at ll ashington, District of Columbia, have inventedcertz'iin new and useful im provoments in Qllools for Removing Valvel'larts of which the following is a specification.

The present invention relates to tools and consists in the combinationsand arrangements oi elements hereinafter described and particularly setforth in the accompanying claims.

1: he. invention has for its purpose to pro vide n tool of thischaracter particularly adapted for use on internal combustion engines ofthe valve-in-the-head-Ltype for removing certain parts of the vaiveactua ing mecliianism; and one which may usefully nerve in various otherWays,

Another object of the invention is to produce a tool for the purposesabove stated which simple in construction, cheap to produce, and whichmay he used Without requiring any special skill.

The invention is disclosed hy way of illustration in the accompanyingdrawing wherein the figure is a perspective view of the tool.

Referring to the construction of the article in further detaih the someconsists of a bar l of tool steel, or other suitable metal for handling:and Whose diniensions in cross-section are sutlicicntto Withstand theuses to which the tool would he ordinarily put. The bod) of the bar 1 isof polygonal design in cross-section whereby the surfaces 2 thereof willa'li'ord suitable Workings; faces to be engaged by a Wrench for turningthe tool when occasion rel un'es.

lue end of the bar 1 is appreciably flat toned as shaped member n andsaid hook is disposed at right angles to the body of a bar and h: s forits function to engage with the rocker arm of.the valve to remove thepush rod of said valve. in its application the hooked member is placedbeneath the rocl er arm and through the leverage ati'orded by the lengthof thc'bar l sutlicicut tension may be exerted against the spring ofsaid valve arm to easily disconnect the rocker arm from its actuatingmcmber.

The opposite end 5 of the bar .[iattcned at 3 and formed to provide ahoolo SIEGNOR D ONE-HALE and tapered extreme end thereof is cated as at6 to provide the pair of Wedgeshaped members 7 as shown. The function ofthe two members 7 is to engage with the tensioning spring of the valve,and the space 6 between said men'ibers affords the neces sary clearancefor the valve stem In oneration the members 7 are inserted betu een thecoils of the spring, and by sullicicnt levof the bar 1 the valve and itscage may be removed.

Another purpose to which the hooked end i of the tool may be put is thatfor turning a wingomt when the latter is located in an ii'iaccessibleplace or requiies great strength to he moved. In such an instance thebifurcated end is simply placed in position to engage the Wing membersof the uutand a wrench applied to the bar when the bar may he turned aswill be understood.

The bar 1. or handle of the tool. is "or polygonal design incrosssection, to the end that the same may be manipulated by the use ofa wrench as will be understood. i tlmn'tlle terminating end of the hookportion is at a-point immediately otisetfrom the juncture of the initialhook portion and the handle.

Another purpose to which the members 7 oi the tool may be put is that oiusing either or both of said members in the capacity of a screw-driverwhen the slot to be engaged is of such dimensions that said members 7may be inserted therein. in this instance also the bar may be turnedstrmucntality of a Wrench.

it is obvious that those skilled in-the art may vary the details ofconstruction and arraugreuu-nt of parts without departing from thespirit of my invention, and therefore I do not wish to be limited tosuch features except as may" be required by the claims.

Having thus fully described my invention. What i claim as new and desireto secure by Letters Patent is:

1. it tool of the character described comprising a handle having one endthereof provided with a hook portion said hook portion beingsubstantially of mi-circular design and dismosed suhstaut ally at rightangles to the central h ritudinai axis of said handle, the end of saidhook terminatsurfaces and the cut away or hittinon opposed throueh theining at a point immediately oil'set from the juncture of the initialhook portion and the handle, substantially as set. forth.

2. A tool of the character described comprising a handle of polygonaldesign in cross-section whereby to be gripped by a manipulating tool,said handle having one end thereof provided with a hook portionsubstantially oi semi-circular design and disposed at right angles tothe central lon- 1 gitudinal axis of said handle, substantially as setforth.

In testimony whereof I affix my signature in the presence of a Witness.
